Hi Mike. Another one for your list. Geraldo's 'Where in the world' is included on the Flapper CD 'Geraldo - Starlight Souvenirs'. There's a copy of it for sale on ebay: https://www.ebay.co.uk/itm/391960397000.

With regard to the sheet music charts, I remember coming across the same pop music history site, and wondering how they'd managed to assign artists to each song (as far as I'm aware the original sheet music charts just listed the song with no artist credit). I thought perhaps they'd just listed every version recorded for each song, but that doesn't seem to be the case. For example 'Arm in Arm' was recorded by Ambrose, Billy Cotton, Syd Lipton, Billy Thorburn, Jack White and Maurice Winnick (and that's only the dance band versions!), yet the site only lists the Ambrose and George Elrick recordings as having charted. I wonder how they chose those two - there must have been some reason!
